肌钙蛋白T与CK-MB对急性心肌梗死诊断价值的探讨

[目的]探讨血清肌钙蛋白T(cTnT)和肌酸激酶同工酶(CK-MB)对急性心肌梗死(AMI)的诊断价值.[方法]检测50例因突发胸痛、胸闷及伴有其他临床症状的急诊患者及30例同期非心血管病对照组患者血清肌钙蛋白T和肌酸激酶同工酶的浓度,并进行分析.[结果]患者组与对照组间cTnT、cK-MB值差异均有显著性意义.在检测的50例cTnT升高的患者中,心肌梗死的患者36例,占72%,同期CM-MB阳性率低于cTnT.[结论]cTnT对心肌梗死的诊断有较高的特异性与敏感性,随着发病时间延长CK-MB的敏感性、特异性逐渐升高.

cTnT and CK-MB'' tests results analysis with 50 cases of AMI

[Objective] To study the value of serum cardiac troponin T(cTnT) and creatine kinase issonzyme MB(CK-MB) in acute myocardial infarction(AMI).[Methods] The concentrations of cTnT and CK-MB in 50 cases of sudden chest pain,emergency patients of other systems and 30 cases of non-heart and vessel diseases were detected.[Results] cTnT and CK-MB had evident difference between patients and control group.AMI patients covered 72% in 50 cases of patients whose cTnT increased.The positivity rate of CK-MB was lower than cTnT.[Conclusion] cTnT has high specificity and sensitivity in the diagnosing AMI.CK-MB's sensitivity and specificity are creasing with the length of time of disease.
